A computing device comprises: a heat sink that has a plurality of cooling fins and a vapor chamber; one or more heat-generating electronic devices that are thermally coupled to the vapor chamber; and at least one cooling fan configured to direct cooling air across the plurality of cooling fins, wherein a first fin included in the plurality of cooling fins and a second fin included in the plurality of cooling fins form a first air passage that has a first air inlet opening and a first air outlet opening, and wherein the first fin is adjacent to the second fin, and a first distance between the first fin and the second fin proximate to the first air inlet opening is less than a second distance between the first fin and the second fin proximate to the first air outlet opening.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The computing device of claim 1, wherein the plurality of cooling fins includes an array of radially diverging fins.
3. The computing device of claim 1, wherein the first air inlet opening has a smaller free area than the first air outlet opening.
4. The computing device of claim 1, wherein at least one of the first cooling fan or the second cooling fan is mounted on the vapor chamber.
6. The computing device of claim 5, wherein the first line is substantially aligned with an airflow direction associated with cooling air flowing through the first air inlet opening.
9. The computing device of claim 8, wherein the first line is substantially aligned with an airflow direction associated with cooling air flowing through the first air inlet opening and the second line is substantially aligned with an airflow direction associated with cooling air flowing through the second air inlet opening.
10. The computing device of claim 1, wherein the one or more heat-generating electronic devices are mounted on a printed circuit board that is coupled to the vapor chamber.
11. The computing device of claim 1, wherein the heat sink, the one or more heat-generating electronic devices, and at least one of the first cooling fan or the second cooling fan is disposed within the display portion of the computing device.
12. The computing device of claim 11, wherein the display portion is configured to be movably coupled to a base portion of a computing device that includes a keyboard.
14. The display of claim 13, wherein the display is configured to be movably coupled to a base of a computing device that includes a keyboard.
15. The display of claim 13, wherein the plurality of cooling fins includes an array of radially diverging fins.
16. The display of claim 13, wherein the first air inlet opening has a smaller free area than the first air outlet opening.
17. The display of claim 13, wherein at least one of the first cooling fan or the second cooling fan is mounted on the vapor chamber.
19. The display of claim 18, wherein the first line is parallel to an airflow direction associated with cooling air flowing through the first air inlet opening.
